Abstract: ABSTRACT OF THE DISCLOSURE           Molding compositions or masses comprising sand and a two-component binder system are prepared.  These two-component binders consist essentially of 1) polyiso-cyanate and 2) a low molecular weight polymethylol pro-duced by the controlled condensation of narrow mole ratios of acetone and formaldehyde under alkaline reaction con-ditions followed by acidification and removal of sufficient water to produce a minimum solid content of at least 95%. These molding compositions cure so fast that they may be taken off the mold five minutes after having been cured with an amine curing agent, and reach a substantial bending strength within minutes of curing compared to prior art compositions which achieve comparable bending strength only after a period of as long as one hour.

Abstract: MULTICHANNEL SEISMIC TELEMETER SYSTEM AND ARRAY FORMER      ABSTRACT OF THE DISCLOSURE         It is a purpose of this invention to dispose a large number, such as 500, of elemental seismic sensor units over the earth's surface in a desired pattern.  The sensors are arranged preferably in a linear pattern, at increasing distances, remote-ly with respect to a central station.  Each elemental seismic sensor unit comprises a short subarray consisting of three seis-mic detectors, electrically interconnected.  Each elemental sen-sor unit is a separate source of seismic signals.  At regular in-tervals the analog seismic signals from the elemental sensor units are sampled in sequence and are digitized as a 20-bit binary num-ber.  The binary numbers are representative of the analog signal levels.  The binary numbers are encoded in a self-clocking re-turn-to-zero pulse code as digital data words.  The data words from the respective elemental sensor units are time-delay multi-plexed into a wide band transmission channel for transmission to the central station in a constant current mode.  Spaced along the transmission link are a series of transceiver units to each of which several separate sensor units are connected.  The trans-ceiver units are connected in series and include a repeater net-work which receives and retransmits data words from down-link transceivers, as well as data words derived from each of the locally-connected sensor units.  Each repeater network also includes a word detection circuit, a local clock, and synchronizing circuitry In the central station, the respective data words are stored as a matrix, in a core memory in sequential order.  A formatter ex-tracts from the core memory, data words that originates from se-lected groups of the elemental subarrays.  The data words are com-bined to form new composite data words representative of seismic signals originating from desired longer arrays.  The composite data words are transferred to a recording medium, such as a magnetic tape, for storage or future use.

Abstract: ABSTRACT OF THE DISCLOSURE               A pulse generator for energizing a coil with periodic bipolar current pulses of predetermined ampli-tude, period and repetition rate and of generally square wave form. The coil to be energized is connected in parallel with a capacitor to form a closed under damped tuned circuit of predetermined  frequency. Current flowing through the coil is suddenly interrupted, causing a sinusoidal  voltage to be generated across the tuned circuit.          The current flowing through the  coil rapidly changes according to a cosine function.  At a time when the current has reached its maximum positive or negative value or slightly before, controlled rectifiers the circuit between the  power source and the tuned circuit are caused to conduct thus maintaining the current in the coil at a level substantially equal to the maximum value.  At the end of a predetermined interval, the supply of direct current to the tuned  circuit again abruptly is interrupted, thus defining another edge of a pulse. The operation is repeated cyclically, and in this manner pulses of generally square wave form are generated periodically.

Abstract: Abstract of the Disclosure A compatable stereophonic television sound trans-mission system for transmitting left and right audio signals in conjuction with a television broadcast wherein video information is conveyed on an amplitude-modulated carrier in a frequency channel having defined frequency limits.  The system includes at a transmitter location a multiplex generator for generating a composite signal having a first component representative of the sum of the audio signals, a second component comprising an amplitude-modulated suppressed carrier subcarrier signal representative of the difference between the audio signals, and pilot component representa-tive of the phase and frequency of the suppressed carrier. The composite signal is utilized to frequency-modulate a sound carrier to develop an RF signal component which is added to the television channel at a discrete frequency spacing from the video carrier.  The system includes at a receiver location a tuner for converting the transmission channel to an inter-mediate frequency, a filter for separating the sound signal therefrom, and a detector for deriving the composite signal from the sound signal.  The composite signal is demodulated in a stereo demodulating stage to develop the left and right audio signal    Improved noise performance is obtained in the system by applying preemphasis to the left and right audio signals,preemphasis of the composite signal, enhance-ment of the second composite signal component, and/or Dolby-B processing of the left and right audio signals or to the com-posite signal.  An adapter is shown for utilizing the system for bilingual programming.

Abstract: ABSTRACT OF THE DISCLOSURE    A flare for the burning of waste gases which is designed to provide a minimum of noise and smoke pollution, comprising a vertical stack having a shroud in the form of a cylinder surrounding, and spaced outwardly from, the top portion of the stack, and extending above the top of the stack.  The space between the shroud and the stack is closed off by an annular plate which serves to support the shroud from the stack.  At the top of the shroud is a steam manifold which carries a plurality of steam nozzles spaced angularly around the inner face of the manifold, so as to direct high velocity steam jets inwardly and upwardly toward the axis of the stack.  The nozzles are placed on the inner face of the manifold so as to be substantially below and inside of the outer contour of the manifold and the shroud.  The outer circumference of the shroud near its bottom end is preforated with a plurality of circumferentially spaced openings through which air can pass to the annular space between the shroud and the stack.  The upwardly moving air mixes with the gas flowing up the stack, and burns in the wind-protected zone above the top of the stack, and below the top of the steam manifold.  Above the top of the steam manifold the jets of steam driving into the rising column of burning gas carry in combustion air and thoroughly agitate and mix the combustion air, the steam, and the burning gas.

Abstract: MULTI-ELEMENT AVALANCHE PHOTODIODE HAVING        REDUCED ELECTRICAL NOISE                        ABSTRACT Avalanche photodiodes include a substrate of a high resistivity material having at least a first surface.  The substrate is of a particular conductivity type.  In the substrate and at the first surface are a plurality of spaced apart regions of the same conductivity type as the substrate and defining the individual photodiode elements of the avalanche photodiode.  Occupying the area at the first surface of the substrate not occupied by the spaced regions and extending into the substrate is a discontinuous layer of the same conductivity type as the spaced regions but of a conductivity concentration much lower than the conductivity concentration of the spaced regions.  On the first surface of the substrate covering the discontinuous layer and slight-ly overlapping the spaced regions is a patterned passivation layer.  The improvement of the present invention over the prior art is the addition of the discontinuous layer which reduces the electrical noise in the output signal of the avalanche photodiode.
